usb: cdns3: change trace event cdns3_ring() operation
the original design seem have several problems, first during trace event
output stage, cdns3_dbg_ring() still refer to priv_ep->trb_pool which
data content may changed during runtime, second when ring number is
greater than TRBS_PER_SEGMENT, it has no change to show "too big" message,
third in cdns3_log_ring event class definition, it allocate too much trace
event buffer.
change cdns3_dbg_ring() to be called at trace event fast assign time, and
change trace buffer real dynamic according ring numbers.
